Cryptocurrency Data Collection

  • Centralized Exchange Scrapers: Collect data from centralized exchanges for cryptocurrencies and other assets (like stocks, futures, and rare earth metals) such as Binance, FTX or Kraken.
  • Decentralized Exchange Scrapers: Collect data from decentralized exchanges on various blockchains by subscribing to swap events in the corresponding LP pools. Examples for sources are Uniswap, curve.finance or PancakeSwap.
  • Bridge Scrapers: Collect swaps data from bridges bridging crypto assets between different blockchains. Examples for sources are Multichain, Anyswap or Hop.

NFT Data Collection

  • NFT Marketplace scrapers: Collect NFT data from various sources. Apart from the collection of attributes through OpenSea API and other sources, they track on-chain NFT transactions from the largest NFT marketplaces to deliver data such as trades, bids and offers. Examples for sources are Opensea, Looksrare and TofuNFT.
